This invention relates to 1 door locking mechanism for house cars andconcerns itself with mechanism that eliminates the usual sealing pin which is frequently lost or thrown away clue to the fact that it becomes frequently detached from its support.

The invention further simplifies the con-p struction of locking mechanism heretofore used and renders the various ways. f V e r i p The invention comprise'sthe novel structure and combination of-parts hereinafter described and more particularly pointed out and defined in the appended claims. y

illustrated consists of a lockingmember .3

which is adapted to be secured to the door 1 by suitable bolts or rivets. This locking member 3 is provided with an apertured lug or staple 4 designed for receiving a Ihasp 5 which is pivoted toa support 6 secured to the a hook which is directed inwardly as shown in FigureSQ The hasp '5has an elongated hook .7. Forwardlyinthe slot Sthere is a stud 9 which is integral with and forms a pivot for a'hook 10. H The pivot pin 9 of the hook 10 has an enlarged head similar, to the one shownupon the hook in Figure 4. It might be mentioned that the pivot 9 is. inserted'through the bearing recess'in the slot and. then, moved forwardly into the narrow portion of the slot before the hasp 5 is ap-' plied to the hook 7, whereby the hook 10 is securely locked to the hasp. The hasp 5 has the usual opening 11 for receiving the lug or staple't. After the hasphas been applied to theflug 4: .thehook 10 is swung through the aperture in said lug to the member 3. The locking memberv 3 is provided withan angular abutment 12 into theangle of which the end of the hook 10 extends when'the same is moved to its locking for locking the has'p 165 other door. The support 6 is provided with Y position. The abutment. 12 and the hook 10 are provided with apertures 13 for the purpose of receiving the usual sealing wireior the like (not shown). L V i Inthe operation of the locking mechanism shown in Figure 1 the doors are brought together-{the haspis then applied to the staple 4, the hook 10 is inserted through the staple and sealed. 7

The pivot 9 of the hook is locked in the slot 8 against removal. It will be appreciated. that there is little "or no liability of the same becoming loose or dissociated from the hasp and being lost.

In the structure shown in Figure 2 the locking mechanism has been modified to lock the doors in partially opened position for ventilating purposes- It will be noted'that the locking member 14: that corresponds to the member 3 is provided with a pairof apertured. lugs or staples 15 which are spaced apart a suitable distanceinaccordance with.

the desired ventilating space between the car doors. Adjacent caching-=15 there is a-sealing lug 12 similar to the one above described.

In this case the hasp 16 is pivoted to the-hook a mannersimilar to the-hook 10 is then engagedwith the staple. Thish ook 10 is also adapted to besealed to the end of the lugs 12 above set forth. 7

The locking mechanism shown in Figure 2 '1s'alsoadapted to lock the car doors in closed position. To do this itis merely necessary to engage the first slot'11 with thefirst staple:

15fand the secondslot 11 with: the second staple '15 when the locking hook 10.will be in position for passing through the second staple15 in'which position it may also be sealedby the second-abutment 12.

' The locking mechanism shown'in Figures 3 and tdifi'er from that shown in Figurel in the omission of'the locking member 3 and the substitution therefor of a'hook-shaped bracket .6 havinga hook 7 In referring to said figures it will be noted that a hookshaped support 6 is also attached to the oppositedoor. A staple carrying'member 17 is pivotally connected to one hook-shaped member and carries astaple 4:.' A hasp 5 and hook 10 arranged as shown and described in connection with Figure 1 is supported by the'other hook-shaped member 6. This modification' shown in Figures. 3 and 4 is, however, similar to the first form, in that the hook 10 ispivotally carried by the hasp 5 and is adapted to be sealedto the lug 13 in its operativeposition asin the first'form.

In" Figures 5 and 6' a further modification has. been illustrated in which one door is equipped with a hook-shaped su'pportfi}, and another door is'equipped with a hook-shaped support 6". The hook-shaped support 6? is adapted to serve as a staple. A slotted hasp 18 is pivoted upon the hook-shapedsupport' 6 and its slotengages. over the other hooksh'ap ed part of memberG. The'hasp 18 carries alo'ckinghooklO asin the first form shown in Figure 1, for locking the hasp upon the staple. In this case the hook 10 is also adapted to be sealed to a lug 13 which is provided upon the hook-shaped member 6.

In Figures 7 and 8 a further modification of the invention has been illustrated. In

this particular modification a-locking member 3 similar to the one shown in Figure 1 is securedto thedoor land a hasp 5 is pivoted uponahook-shaped support 6 upon the door 2for engaging the staple 4. This hasp does not support the hook as in certain of the other modifications. In Figure 7 the locking hook, which is designated by the reference numeral 19, is pivoted ,coaXially with the hasp 5 upon the hook bracketG. This modification offers some advantages in thatthe hasp 5 and the locking hook 19 may be simultaneously hung on the hook bracket 6.

In Figures 9 and 10 a still further modification of the invention has been illustrated. In this modification, the lockinghookQO is carried by a stationary locking member 6 which is securediupon the door'l; instead of bei-ng carried by the hasp. Referring to said [figures it will be noted that a hasp 21is pivoted at one end to a hook-shaped support 6 similar to the one shown in Figures 5 and 6 and this hasp 21 engages over a staple 22 formed upon thestationary locking member 6. This looking member 6 is provided with a bayonet slot 6 for receiving the headed pivot pin 20 on the locking hook 20. v The hook 2O isv adapted for engaging beneath the staple 22' when the hasp 21'has' been applied-thereto and the same may be sealed to the lug'13 as in'the other forms illustrated.

It will be appreciated that. according to this invention the oldform of sealing pin that has been heretofore used and which has proven objectionable in that it frequently became dissociated from its sliding pivots and was lost or thrown away is eliminated. In the present instance the different forms-of locking hooks are adapted to be permanently associated with parts of the locking mechanism,--and thereis less or no liability of their being lost or thrown away by careless workmen sincethey are locked against accidental removal. 7

e are aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted hereon, otherwise than necessitated 'by the priorart.

7 WVe claim as our invention:

--1. In a car door latching mechanism, a pivot support, a hasp having a bearing recess for receiving said support and having a forwardly extending restricted slot, and alatch hook having a headed stud extending through said slot and locked from removal by said pivot support.

2. In a car door latching mechanism, a hasp having a bearing recess terminating in a restricted slot, in combination witha latching hook having a headed. stud insertable through said bearing recess and slidable into said restricted slot, and a pivot stud entering said bearing recess and preventing the removal of said latching hook.

3. An article of manufacture comprising a hasp having a bearing. recess terminating in a restricted slot in combination with a latching hook having a headed stud insertable through said bearing recess and slidable into said restrictedslot.

In testimony whereof, we have hereunto subscribed our names.
